Axis mode
The spindle can be switched from spindle mode to axis mode (rotary axis) if the same motor
is used for spindle and axis operation.
Switching between spindle modes
Switching between spindle and axis operation can be done as follows:

The spindle changes to oscillation mode if a new gear step has been specified using
automatic gear step selection (M40) in conjunction with a new S-value or by M41 to M45.
The spindle only changes to oscillation mode if the new gear stage is not equal to the
current actual gear stage.
When the new gear is engaged, the interface signal:
DB31, ... DBX84.6 (Oscillation mode)
is reset and the interface signal:
DB31, ... DBX16.3 (Gear changed)
is used to go to control mode.
The last programmed spindle speed (S-value) is activated.
